As part of Lab Week, our Lab4Life feature hosts a special series highlighting the inspiring journeys of scientists dedicated to clinical science and global health. In this guest blog, microbiologist Tresford Bwale shares his frontline experiences in diagnostic microbiology, from combating outbreaks to mentoring future scientists, and reflects on the critical role laboratory professionals play in safeguarding public health
Medical Laboratory Professionals Week is a time to reflect on the unseen efforts behind every diagnostic result and medical breakthrough. As a microbiologist, my work revolves around tracking pathogens, supporting clinical decisions, and collaborating with teams that make a real difference in public health.
Challenges and triumphs in the lab
Working as a laboratory professional, I've faced my share of challenges — from handling high sample loads during outbreaks like anthrax to navigating tight timelines for critical diagnostic reports. Despite these hurdles, each day brings a sense of accomplishment, especially when we successfully isolate a pathogen or support timely patient treatment.
Mentorship and inspiration
One of my greatest inspirations has been a senior microbiologist at the Tropical Diseases Research Centre, who not only mentored me during my early days but also instilled a culture of curiosity and persistence. Their passion for research and dedication to One Health surveillance across human and animal health has greatly influenced my career direction.
Our work’s impact on healthcare
Teamwork in action: Microbiologists working on media preparation and sample analysis
My contributions have spanned surveillance of antimicrobial resistance (AMR), malaria diagnostics at Ndola Teaching Hospital, and anthrax genome sequencing. Whether it’s confirming a bacterial pathogen in a clinical specimen or contributing to national AMR surveillance, my role helps safeguard public health across Zambia.
Looking ahead
As we continue to face emerging health threats, our labs must stay adaptive. I aim to deepen my research in AMR genomics, while also advocating for stronger lab networks and policies that support One Health surveillance. Together, we can advance diagnostics, improve response systems, and empower the next generation of lab scientists.
